New Enhanced Compact Surge Protection up to 32A


The latest D/DS range is designed to complement the existing D1 Series of ESP products providing a further enhanced series to our existing ESP range of mains protector range for specific systems.


The new ESP D/DS Series now offers industry leading low let through voltage combined with the mains test Type 1, 2 & 3 (to BS EN 61643). Designed for use on low current single phase systems (up to 10A or 32A) to protect against transient overvoltages on the mains supply, as well as offering increased exposure level covering lightning protection zones (LPZ) 0 - 3.

It also features a three way visual indication of protector status and advanced pre-failure warning, as well as remote indication facilities to a BMS via a Volt-Free contact, so you need never be unprotected.

Features & benefits:

Combined type 1, 2 & 3 tested protector (to BS EN 61643)

For use on low current (up to 10A or 32A) single phase systems, to protect against transient overvoltages on the mains supply.

Very low let through voltages

Protecting essential equipment by restricting transient overvoltages to a safe level.

Industry leading, enhanced protection to BS EN 62305

Minimising the risk of dangerous sparking (leading to flash over and electrical shock hazards) as well as equipment damage compared to standard protection.

Compact DIN housing

Mounts to standard 35mm top hat DIN utilising DIN foot with locking feature.

Three way indication facility (DS Version)

A flashing warning of potentially fatal neutral to earth supply faults as well as a Volt-Free contact to show pre failure warnings and potential phase loss. (Due to incorrect earthing, wiring errors or unbalanced conditions.)

Remote indication facility

Protectors linked to building management systems (BMS) for clear remote failure warning via an active change over Volt-Free contact.

Repeat protection in lightning intense environments

Protectors offer repeated protection against transient overvoltages, with a 5 year warranty
